To all whom it may concern: I Be it known that I, GUs'rAvn. RADER,a

quick andeffective manner, and at a considerable saving in time and labor; and for this pur ose the invention consists of a molding tab e for making plaster-boards which comprises a" table, means for supplying a layer of paper or fabric over the entire length of the table, J gage-barsguided along the sides of the table, means for locking the gage-bars at a certain height above the table according to the thickness of the plasterboards to be made, and transverse dividing rods inserted in openings of thegage-bars for defining the length of the plaster-boards and permitting the convenient separation ofv the same;

The invention consists further of certain details of construction and combinations of.

parts which will be fully described herein- 3 after and finally pointed out in the claims.

In the accompanying drawings,-=Figure 1 represents a perspective view of mly imroved molding table for making p asteroards, Fi 2 is a detail vertical transverse section. on inc 2, 2, Fig. 1, showing the con-' .nection of the gage-bars with the sides of the molding table, 3 is a side-elevation ofan end-portion of the molding table, drawn on a larger scale, and Fig, 4 is an end-eleva tion of the table partly in section through' the setting-lever of one of the gage-bars Fig. 5 is a detail-showing means used to drive the rolls by which the paper is fed or sup-- plied over the length of the table.. 1

Similar letters of reference indicate corresponding parts throughout the several views. Referring to the drawings, a represents a table which is equal in width to the width of the plaster-boards'to be'made, and of a length equal to the length of say five" laster-.. boards. At the rear-end of the tab e a are Letters Patent. Patented April 14:, 1908;

' r ofpaper, muslin or other fabric 1), and

adjacent thereto. are supported on the table in suitable bearings two guiderollers .b I) through which the paper or other fabric p is uided until it is drawn out over the full engthof the table for entirely covering the same.

table are arranged two gage-bars d d, which are whic are guided by inclined s ots d it'ma.

be friction tight, on headed screw-studsi which are attached to the side-timbers of the table, washers d being interposed between the ga e-bars d and the heads of the screw- -studs 2 so as to permit the free motion of the gage-bars along the sidesof the table. side-timbers of the table a are rovided throughout their length with metal ic plates (1 for reducing the friction of the gage-bars with the side-timbers of the table and permitting the easy adjustment of the gagebars on the side-timbers. The front-ends of the gage-bars dare extended beyond the front-end of the tables and connected by To opposite sides of the table and. normally on a level with the surface of the referably made of wrou ht iron, and 1 means of pivot-bolts e; that pass through holes in thegage-bars with slots 6 in two handle-levers f which; are pivoted .at their lower ends to perforated ears 3 attached to the lower parts of the front legs of the table, as shown clearly in Fig. 3.

At distances corresponding to the length of the plaster-boards are inserted into corresponding holes of the gage-bar'sd transverse.

rods 9, of round or other'cross-section, which are preferably tapered at one end and bent at right an les at. the opposite end so as to form hand es g. The pointed ends serve for facilitating the insertion of the rods g, while the bent ends g serve as handles n assing the rods through the holes of the gage bars and for turning the same on theiraxes after theplaster-bosirds are formed on the table. J m, Fig. 5, 'indicates a driving crank for rolls 1).

The gage-bars d are r'aised by means of the hand-levers f along their guideisl'ots to such an extent that their upper edges are at such a i height abovethe surface of the table'as is required for the thickness of theplaster bpards to be made. The gage-bars 11', are

then locked in'the required position by pivot hooks h on the hand-leversf, which hooks enr gage holes-h: in fianged-platesh attached tq,.'

the front-legs of the table a. The transverse separating rods g are table through the holes in the gage-bars, as shown in Figs. 1 and 2.

strengthening material, is then spread over the paper or other fabric covering the surface of the table to e-bars and separating rods g, and care uniform thickness. 'VVhen the plaster-mass has partly set, the transverse separatingrods are taken hold of at their turned on their axes by means of their handle-ends 9 so as to get loose from the partly-set mass of plaster. rods are then removed; The then permitted to harden. are then lowered so as plaster-mass The gage bars to expose the sides of The plaster, which boards, is mixed with hair, fibers or other fibrous length the upper edges of the l trimmed so as to form plaster-boards of face-layer of paper over 1 The separating length for making a senses j claim as new and desire to secure by Letters then placed across the Patent:

molding table for making plasterconsisting of a table of sullieient for making a plurality of plasterboards, gageshars at opposite sides of the table, means for adjusting the gage-ha rs to project to the required degree above the sur-- face of the table, means for supplying a surhe full length of the table, and transverse separating rods iuserted at uniform distances from each other handles and into the upper portions of the gage-liars 2. A molding table for making plasterboards, consisting of a table of snllicient plurality of plasterboards, gage-bars located at opposite sides of the table, means for guiding the gage-bars along the sides of the table, means eoi'iueetml the body of plaster. Thenv one plasterwith the gage-bars for adjusting the gageit over and breaking the fabric at the points below the indentations formed by the separating rods, which is readily accomplished by bending up first one lower or higher relatively to the surface layer of paper or of the table. and. transverse separating rods passing through holes in the upper portions of the gage-bars.

3. A molding table for making plasterplaster-board and breaking the connecting boards, consisting of a table of sutlieient fabric at the line of demarcation between the length-for making a plurality of plaster first and second plaster-board formed by the boards, gage-bars located at the sides of the separatingrod, after which the rod and the -table, means for raising or lowering the gageboard are removed and so on, breaking off bars along the sides ol the table relatively hr one plaster-board after the other, until all the plaster-boards are removed from the table.

The finished plaster-boards are then piled up and are used directly with the face-layer normal size of by 36 inches} When longer plaster-boards are to be made,

then the distance between the separating rods has to be made correspondingly longer. v

The advantages of my improved molding table for making plaster-boards are, first, that a number of plaster boards can be made at one operation, so that the expense of the same is reduced; second,. that the'molding table requires no cleaning after each operation as the face-layer of paper or fabric over the front-end of the table and which the plaster-mass is spread, keeps the ends oi table perfectly clean, and immediately ready for the next operation, whereby considerable time is saved as-compared with the molding tables for sin le plaster-boards heretofore in use; and, tiird, that the plasterboards made on the improved molding table do not require any trimming or finishing opthe surface of the s:une,,ineans for looking the gagebars after adjustment, and transverse separating rods supported by said gagebars.

transverse separating rods passing through holes in the upper portions of the gage-liars. 5.
